Air conditioning for homes and businesses in Dulwich
We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. The survey ends with a recommendation and the reasons for it, along with the manufacturer’s warranty terms on your quote. A lot of the calls we get from Dulwich are about one room that is too hot to sleep or work in. That’s usually a single wall-mounted split, from £1,200 + VAT.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes about a day for a single-room system, longer for multi-room and ducted systems. Parking bays, permits and roof or balcony access are the first things we ask about in Dulwich.
- First comes a site survey, or pictures and measurements for a straightforward job.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Move furniture away from the wall where we will be working

Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

How the job changes from property to property
Pipework and condensate drains
After the pipework is fitted, the refrigerant circuit is pressure tested and evacuated, so the system starts life clean, dry and leak-tight. It’s recorded in the commissioning details.
Multi-split systems
You can mix indoor unit types on many multi-split systems, choosing what suits each room, as the manufacturer allows. We plan the mix on the survey.
Homes in Dulwich and air conditioning
VOA council tax data put about 73% of homes in and around Dulwich before 1919, and about 54% of households live in flats, according to the last census (2021). Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. London installs often hinge on outside space, the lease and access to the building.
Kingswood House, about 1.1 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. Around Christ's Chapel of God's Gift, a quick check of the listing and conservation maps is part of planning any install.

Other services in Dulwich
Managing agents and facilities teams in Dulwich
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.
Looking after it afterwards
After the visit, a few habits help:
- Keep to the service interval the manufacturer recommends
- Flag any change in how the system sounds or performs
- Choose a comfortable set temperature rather than the lowest
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings, so you are confident using it.
Book an annual service. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early and keeps the warranty paperwork right where servicing is a condition.
Dulwich questions
Is Dulwich in your area for air conditioning?
Yes, Dulwich is within the area we cover. Tell us a little about the job and we will take it from there.
Can I fit air conditioning in Dulwich without planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Dulwich is in the Dulwich Wood Conservation Area. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the planning department at Southwark council, normally the authority for Dulwich.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Can you fit air conditioning in a leasehold flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
